PROBLEM TO BE SOLVED: To provide an air conditioning duct for a vehicle capable of fully achieving performance of a resonator while restricting generation of prevailing sound. SOLUTION: In this air conditioning duct provided with the resonator, a duct main body 1 is formed in such a way that a circumferential edge 10 of an opening c of the duct main body 1 connected to the resonator 2 overhangs outward at a downstream side opening edge part more than at an upstream side opening edge part. In addition, a line m1 connecting a circumferential edge point 11 positioned on the most upstream part of the opening c to a circumferential edge point 12 positioned on the most downstream part is expanded outward of the duct at an angle of θ1 toward the downstream side of the duct main body to a center axis n of the duct main body 1. In this, 1.5 deg.<=θ1<=5 deg. is satisfied. |
